56 Nor do they hold in greater account the authority of the Church and of the Supreme Pontiff whenever efforts are made to bring them to a better sense, although at times as far as words go they are lavish of promises of submission as long as they can hope to hide themselves behind these and gain credit and protection. This contempt almost bars the way of all wellfounded hope of the conversion of the erring; while they refuse obedience to him "to whom Divine Providence as to the Lord and Father of the whole Church in its pilgrimage on earth . . . has entrusted the custody of Christian life and faith and government of His Church; wherefore when anything arises in the Church against the Catholic faith to no other authority but his is it to be rightly referred for correction, and to no other with such certainty as to him has it been shown what answer is to be made to error in order that it may be examined by his prudence" ( Ibid . cap. 2). And would to God that these poor wanderers on whose lips one so often hears the fair words of sincerity, conscience, religious experience, the faith that is felt and lived, and so on, learned their lessons from Anselm, understood his holy teachings, imitated his glorious example, and, above all, took deeply to heart those words of his: "First the heart is to be purified by faith, and first the eyes are to be illuminated by the observance of the precepts of the Lord . . . and first with humble obedience to the testimonies of God we must become small to learn wisdom . . . and not only when faith and obedience to the commandments are removed is the mind hindered from ascending to the intelligence of higher truths, but often enough the intelligence that has been given is taken away and faith is overthrown, when right conscience is neglected" ("De Fide Trinitatis," cap. 2).
